SHAFT==HANGER.

SPECIFICATION forming part of Letters Patent No. 383,532, dated May 29, 188.8.

Application filed August 21, 1886. Renewed March 15, 1888. Serial No. 267,284. (No model.)

To all whom it may concern:

Be it known that I, AUGUST Lonnwna, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Shaft- Hangers, of which the following is aspeeification, reference beinghad therein to the accom panying drawings, in which Figures 1 and 2 represent front and side views, respectively, of a shaft-hanger provided with my improvements. Fig. 3 is a sectional elevation showing certain details ofthe device. Fig. 4. represents a vertical section of the cylinder which carries the shaft box and other details. Fig. 5 shows in plan the upper and lower parts of the shaft-box. Fig. 6 shows in plan and end viewsthe fixed receiving-plate to which the hanger is adjustably secured. Fig. 7 illustrates in section the attachment of the hanger to the receivingplate. Fig. 8 represents a cross-section taken on line :0 0c of Fig. 7. Fig. 9 is a plan of the grooved lower side of the hanger base-plate.

A designates a tubular column projecting downward from a base-plate which is secured above, as hereinaftersetforth.

\Vithin the column A is placed a tube, 13, which is constructed to be moved up and down therein, said tube being screw-threaded from its lower end upward a suitable distance for the attachment of the devices for holding and regulating the position of the shaft box. WVithin an enlargement at or near the lower end of the column A are placed two curved plates, at, which conform to the tube B and may be closed against it by means of the set-screws b, so that the tube may be firmly fastened at any desired elevatiombeing let down or raised, as desired.

0 indicates a cylinder which carries the shaft-box, the said cylinder being constructed to be moved up and down on the tube B,which passes through it, as shown. The shaft-box is constructed in two main parts-the upper part, D, and the lower part, D. The lower part is provided with brackets (I, having a back plate, 6, which has formed thereon a circular conical projection, f, which fits in a correspondingly-shapcd socket, g, in the front of cylinder 0. The projectionfand recess 9 are preferably made in the annular form with beveled surfaces, as shown in the drawings, and the parts O and e are secured together by means of a boltand nut, h, said bolt extending through a central aperture in plate 6 into the front part of the cylinder. The said cylinder may be fixed on the tube B, as to elevation, by means ofthe threaded rings 0, one of which is placed on the threaded tube above and the other below the cylinder, as shown.

The two parts D and D of the shaft-box are each divided by partitions so formed that the two parts may be closed about a shaft, and when so closed several annular chambers are formed around the shaft. As shown in the drawings, the shaft-box is provided with five chambers, the central chamber, i, being intended to contain lubricating material, the chambers i, one being at each side of the central chamber, to receive Babbitt or other suitable metal, and the outmost chambers, i", to form, in conjunction with end plates, 70, stuffing-boxes at the ends of the shaftbox.

The end plates, it, have each a circular opening for the shaft and a tubular projection, m, on the inner side surrounding such opening, and when the plates are adjusted in place the tubular projections extend into the shaft-box,

the plates being closed against it and secured by screws or.

The parts D and D areprovidcd with flanges 0, the flange of the lower part having a rim, 0, along its edge, within which the flange of the upper part fits, and in adjusting the shaftboX on a shaft a thin layer of rubber packing is laid along on the lower flange 0 within the rim, so that a closejoint is formed between the flanges when the two parts of the box are brought together and secured by screws 19. A little cotton packing is then wound upon the shaft at each end of the box. The plates it, having been placed on the shaft, are pressed to the shaft-box, the tubular parts at entering the same at its extremities and driving the packing into the striding-boxes, and the plates being firmly secured to the box by the screws 'n. The lubricating matter is introduced into the middle chamber, 11, through a central aperture, g, which is closed with a screw'plug which has a fine hole, through which air may be admitted for necessary pressure. Thus a close solid shaft'box is constructed well adapted to prevent the escape of lubricating matter at any point, such matter resting against and around the shaft in the central part of the box, and a lengthened bearing is provided, the bearing parts being in the tubular parts of the plates It, causing very little friction, preventing vibration, and giving the shaftgreat steadiness.

E designates the base-plate of the column A, which depends therefrom.

G is a supporting-plate, which is secured to the timbers of a floor above, or otherwise sustained, said plate being provided at its edges with the housings 1'. These housings form rctainingguides for the hanger base-plate E, which slides between them and may be moved in either direction. Within the recesses s of the housings are placed blocks 3, which may be pressed by the screws and thus clamp the base-plate after 'the hanger has been'moved to position as desired. lhe parts ofthe clampblocks 3 which close against the hanger baseplate are beveled and lit in corresponding longitudinal grooves, 3 in the base-plate, so that the clamp-blocks, moving in said grooves when the hanger is being adjusted, are prevented from getting out of place. An additional screw, it, passingthrough plaleE, serves to readily fasten the plate when moved to the proper point.

By means of the plates E and G and the clamping devices the hanger may be moved forward or backward and secured so that the shaft-box is exactly in line, and by means of the column A, tube B, and the clamping devices formed by curved plates to and screws b the cylinder carrying the shaft box may be adjusted vertically. 'When a slight vertical adjustment of cylinder 0 is desired, such may be readily effected by means of the threaded rings a on tube 13. The cylinder may also be turned to change the position of the shaftbox and then secured by means of the rings 0, and by means of the pivotal connection at it between cylinder 0 and the shaft-box the shaft may be adjusted at any desired inclination.

Having described my invention, I claim 1. In a shafthanger, a shaft-box provided with a vertical plate having a circular conical projeetiomf, iii combination with a vertical cylinder which is adjustable on a depending tube, said cylinder being provided with a lat eral socket on one side corresponding with said conical projection, and a central securing-bolt, substantially as and for the purposes described.

2. In combination with aihollow depending column, a vertical tube, B, adjustabl y secured therein, cylinder 0, adjustable on said tube and provided with a lateral socket, g, a shaftbox provided with brackets projecting from a vertical plate, 6, which has a circular conical projection, f, which fits in socket g, and a central securing-bolt, h, substantially as set forth and described.

3. In combination with a hanging column provided with a grooved base-plate, E, a fixed plate provided with recessed retaining-hcusings, in which are placed removable beveled elampingblock-s s, which extend into correspondingly-shaped grooves in the base-plate, and screws for pressing the clamping-blocks, substantially as set forth and described.

4. In a shaft-hanger, a shaft-box the shell of which is constructed in two parts, which are provided with partitions constructed to form annular chambers around a shaft, end plates, 7c, provided with tubular extensions to enter chambers for stuffing-boxes at the ends of the shaft-box, and securingbolts, all combined substantially as set forth and described.

5. The shaft-box constructed in two parts, provided with flanges 0 and rim 0, with suitable packing between the flanges, the two parts of the box being provided with partitions constructed to form a central annular chamber about the shaft for lubricating matter, a chamber at each side of-said central chamber for filling metal, and a chamber at each end of the shaft-box to form a stuffingbox, in combination with end plates, 70, provided with tubular extensions, substantially as and for the purposes described.

In testimony whereof I have affixed my signature in presence of two witnesses.

AUGUST LOEHNER.
